What is Levofloxacina Loxadin?

Levofloxacina Loxadin injection is used to treat bacterial infections in many different parts of the body. It is also used to prevent an anthrax infection after a person has been exposed to anthrax. Levofloxacina Loxadin is also used to treat and prevent plague (including pneumonic and septicemic plague).

Levofloxacina Loxadin belongs to the class of medicines known as quinolone antibiotics. It works by killing bacteria or preventing their growth. However, Levofloxacina Loxadin will not work for colds, flu, or other virus infections.

Levofloxacina Loxadin is to be given only by or under the direct supervision of your doctor.

Levofloxacina Loxadin indications

An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Levofloxacina Loxadin Tablets, USP and other antibacterial drugs, Levofloxacina Loxadin Tablets, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Levofloxacina Loxadin Tablets, USP is indicated for the treatment of adults (≥18 years of age) with mild, moderate, and severe infections caused by susceptible isolates of the designated microorganisms in the conditions listed in this section.

Culture and susceptibility testing

Appropriate culture and susceptibility tests should be performed before treatment in order to isolate and identify organisms causing the infection and to determine their susceptibility to Levofloxacina Loxadin Tablets, USP. Therapy with Levofloxacina Loxadin Tablets, USP may be initiated before results of these tests are known; once results become available, appropriate therapy should be selected.

As with other drugs in this class, some isolates of Pseudomonas aeruginosa may develop resistance fairly rapidly during treatment with Levofloxacina Loxadin Tablets, USP. Culture and susceptibility testing performed periodically during therapy will provide information about the continued susceptibility of the pathogens to the antimicrobial agent and also the possible emergence of bacterial resistance.

Nosocomial Pneumonia

Levofloxacina Loxadin Tablets, USP is indicated for the treatment of nosocomial pneumonia due to methicillin-susceptible Staphylococcus aureus, Pseudomonas aeruginosa, Serratia marcescens, Escherichia coli, Klebsiella pneumoniae, Haemophilus influenzae, or Streptococcus pneumoniae. Adjunctive therapy should be used as clinically indicated. Where Pseudomonas aeruginosa is a documented or presumptive pathogen, combination therapy with an anti-pseudomonal β-lactam is recommended.

MDRSP isolates are strains resistant to two or more of the following antibacterials: penicillin (MIC ≥2 mcg/mL), 2nd generation cephalosporins, e.g., cefuroxime, macrolides, tetracyclines and trimethoprim/sulfamethoxazole.

Acute Pyelonephritis: 5 or 10-day Treatment Regimen

Levofloxacina Loxadin Tablets, USP is indicated for the treatment of acute pyelonephritis caused by Escherichia coli, including cases with concurrent bacteremia.

Uncomplicated Urinary Tract Infections

Levofloxacina Loxadin Tablets, USP is indicated for the treatment of uncomplicated urinary tract infections (mild to moderate) due to Escherichia coli, Klebsiella pneumoniae, or Staphylococcus saprophyticus.

Inhalational Anthrax (Post-Exposure)

Levofloxacina Loxadin Tablets, USP is indicated for inhalational anthrax (post-exposure) to reduce the incidence or progression of disease following exposure to aerosolized Bacillus anthracis. The effectiveness of Levofloxacina Loxadin Tablets, USP is based on plasma concentrations achieved in humans, a surrogate endpoint reasonably likely to predict clinical benefit. Levofloxacina Loxadin has not been tested in humans for the post-exposure prevention of inhalation anthrax. The safety of Levofloxacina Loxadin in adults for durations of therapy beyond 28 days or in pediatric patients for durations of therapy beyond 14 days has not been studied. Prolonged Levofloxacina Loxadin therapy should only be used when the benefit outweighs the risk.

Plague

Levofloxacina Loxadin Tablets, USP is indicated for treatment of plague, including pneumonic and septicemic plague, due to Yersinia pestis (Y. pestis) and prophylaxis for plague in adults and pediatric patients, 6 months of age and older. Efficacy studies of Levofloxacina Loxadin could not be conducted in humans with plague for ethical and feasibility reasons. Therefore, approval of this indication was based on an

efficacy study conducted in animals.

Levofloxacina Loxadin is used to treat bacterial infections of the respiratory tract, urinary tract, ear, tooth and prostate gland. It is also used to treat skin and soft tissue infections, anthrax and plague.

Its empirical formula is C18H20FN3O4·½H2O and its molecular weight is 370.38.

Levofloxacina Loxadin is a light yellowish-white to yellow-white crystal or crystalline powder. The molecule exists as a zwitterion at the pH conditions in the small intestine. The data demonstrate that from pH 0.6-5.8, the solubility of Levofloxacina Loxadin is essentially constant (approximately 100 mg/mL). Levofloxacina Loxadin is considered soluble to freely soluble in this pH range, as defined by USP nomenclature. Above pH 5.8, the solubility increases rapidly to its maximum at pH 6.7 (272 mg/mL) and is considered freely soluble in this range. Above pH 6.7, the solubility decreases and reaches a minimum value (about 50 mg/mL) at a pH of approximately 6.9. Levofloxacina Loxadin has the potential to form stable coordination compounds with many metal ions. This in vitro chelation potential has the following formation order: A1+3 > Cu+2 > Zn+2 > Mg+2 > Ca+2.

Dosage in Adult Patients with Normal Renal Function

The usual dose of Levofloxacina Loxadin Tablets, USP is 250 mg, 500 mg, or 750 mg administered orally every 24 hours, as indicated by infection and described in Table 1.

These recommendations apply to patients with creatinine clearance ≥ 50 mL/min. For patients with creatinine clearance <50 mL/min, adjustments to the dosing regimen are required.

Dosage in Pediatric Patients

The dosage in pediatric patients ≥ 6 months of age is described below in Table 2.

Dosage Adjustment in Adults with Renal Impairment

Administer Levofloxacina Loxadin Tablets, USP with caution in the presence of renal insufficiency. Careful clinical observation and appropriate laboratory studies should be performed prior to and during therapy since elimination of Levofloxacina Loxadin may be reduced.

No adjustment is necessary for patients with a creatinine clearance ≥ 50 mL/min.

In patients with impaired renal function (creatinine clearance <50 mL/min), adjustment of the dosage regimen is necessary to avoid the accumulation of Levofloxacina Loxadin due to decreased clearance.

Levofloxacina Loxadin Tablets, USP should be administered at least two hours before or two hours after antacids containing magnesium, aluminum, as well as sucralfate, metal cations such as iron, and multivitamin preparations with zinc or didanosine chewable/buffered tablets or the pediatric powder for oral solution.

Administration Instructions

Food and Levofloxacina Loxadin Tablets, USP

Levofloxacina Loxadin Tablets, USP can be administered without regard to food.

Hydration for Patients Receiving Levofloxacina Loxadin Tablets, USP

Adequate hydration of patients receiving oral Levofloxacina Loxadin Tablets, USP should be maintained to prevent the formation of highly concentrated urine. Crystalluria and cylindruria have been reported with quinolones.

Levofloxacina Loxadin interactions

Oral Solution

While the chelation by divalent cations is less marked than with other fluoroquinolones, concurrent administration of Levofloxacina Loxadin

Oral Solution with antacids containing magnesium, or aluminum, as well as sucralfate, metal cations such as iron, and multivitamin preparations with zinc may interfere with the gastrointestinal absorption of Levofloxacina Loxadin, resulting in systemic levels considerably lower than desired. Tablets with antacids containing magnesium, aluminum, as well as sucralfate, metal cations such as iron, and multivitamin preparations with zinc or didanosine may substantially interfere with the gastrointestinal absorption of Levofloxacina Loxadin, resulting in systemic levels considerably lower than desired. These agents should be taken at least two hours before or two hours after oral Levofloxacina Loxadin administration.

Warfarin

No significant effect of Levofloxacina Loxadin on the peak plasma concentrations, AUC, and other disposition parameters for R- and S- warfarin was detected in a clinical study involving healthy volunteers. Similarly, no apparent effect of warfarin on Levofloxacina Loxadin absorption and disposition was observed. However, there have been reports during the postmarketing experience in patients that Levofloxacina Loxadin enhances the effects of warfarin. Elevations of the prothrombin time in the setting of concurrent warfarin and Levofloxacina Loxadin use have been associated with episodes of bleeding. Prothrombin time, International Normalized Ratio (INR), or other suitable anticoagulation tests should be closely monitored if Levofloxacina Loxadin is administered concomitantly with warfarin. Patients should also be monitored for evidence of bleeding.

Antidiabetic Agents

Disturbances of blood glucose, including hyperglycemia and hypoglycemia, have been reported in patients treated concomitantly with fluoroquinolones and an antidiabetic agent. Therefore, careful monitoring of blood glucose is recommended when these agents are co-administered.

Non-Steroidal Anti-Inflammatory Drugs

The concomitant administration of a non-steroidal anti-inflammatory drug with a fluoroquinolone, including Levofloxacina Loxadin, may increase the risk of CNS stimulation and convulsive seizures.

Theophylline

No significant effect of Levofloxacina Loxadin on the plasma concentrations, AUC, and other disposition parameters for theophylline was detected in a clinical study involving healthy volunteers. Similarly, no apparent effect of theophylline on Levofloxacina Loxadin absorption and disposition was observed. However, concomitant administration of other fluoroquinolones with theophylline has resulted in prolonged elimination half-life, elevated serum theophylline levels, and a subsequent increase in the risk of theophylline-related adverse reactions in the patient population. Therefore, theophylline levels should be closely monitored and appropriate dosage adjustments made when Levofloxacina Loxadin is co-administered. Adverse reactions, including seizures, may occur with or without an elevation in serum theophylline levels.

Cyclosporine

No significant effect of Levofloxacina Loxadin on the peak plasma concentrations, AUC, and other disposition parameters for cyclosporine was detected in a clinical study involving healthy volunteers. However, elevated serum levels of cyclosporine have been reported in the patient population when coadministered with some other fluoroquinolones. Levofloxacina Loxadin Cmax and ke were slightly lower while Tmax and t½ were slightly longer in the presence of cyclosporine than those observed in other studies without concomitant medication. The differences, however, are not considered to be clinically significant. Therefore, no dosage adjustment is required for Levofloxacina Loxadin or cyclosporine when administered concomitantly.

Digoxin

No significant effect of Levofloxacina Loxadin on the peak plasma concentrations, AUC, and other disposition parameters for digoxin was detected in a clinical study involving healthy volunteers. Levofloxacina Loxadin absorption and disposition kinetics were similar in the presence or absence of digoxin. Therefore, no dosage adjustment for Levofloxacina Loxadin or digoxin is required when administered concomitantly.

Probenecid And Cimetidine

No significant effect of probenecid or cimetidine on the C of Levofloxacina Loxadin was observed in a clinical study involving healthy volunteers. The AUC and t½ of Levofloxacina Loxadin were higher while CL/F and CLR were lower during concomitant treatment of Levofloxacina Loxadin with probenecid or cimetidine compared to Levofloxacina Loxadin alone. However, these changes do not warrant dosage adjustment for Levofloxacina Loxadin when probenecid or cimetidine is co-administered.

Interactions With Laboratory Or Diagnostic Testing

Some fluoroquinolones, including Levofloxacina Loxadin, may produce false-positive urine screening results for opiates using commercially available immunoassay kits. Confirmation of positive opiate screens by more specific methods may be necessary.

Development of Drug Resistant Bacteria

Hypotension has been associated with rapid or bolus intravenous infusion of Levofloxacina Loxadin. Levofloxacina Loxadin should be infused slowly over 60 to 90 minutes, depending on dosage.

Crystalluria and cylindruria have been reported with quinolones, including Levofloxacina Loxadin. Therefore, adequate hydration of patients receiving Levofloxacina Loxadin should be maintained to prevent the formation of a highly concentrated urine.

Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The data described below reflect exposure to Levofloxacina Loxadin in 7537 patients in 29 pooled Phase 3 clinical trials. The population studied had a mean age of 50 years (approximately 74% of the population was < 65 years of age), 50% were male, 71% were Caucasian, 19% were Black. Patients were treated with Levofloxacina Loxadin for a wide variety of infectious diseases. Patients received Levofloxacina Loxadin doses of 750 mg once daily, 250 mg once daily, or 500 mg once or twice daily. Treatment duration was usually 3 to 14 days, and the mean number of days on therapy was 10 days.

The overall incidence, type and distribution of adverse reactions was similar in patients receiving Levofloxacina Loxadin doses of 750 mg once daily, 250 mg once daily, and 500 mg once or twice daily. Discontinuation of Levofloxacina Loxadin due to adverse drug reactions occurred in 4.3% of patients overall, 3.8% of patients treated with the 250 mg and 500 mg doses and 5.4% of patients treated with the 750 mg dose. The most common adverse drug reactions leading to discontinuation with the 250 and 500 mg doses were gastrointestinal (1.4%), primarily nausea (0.6%); vomiting (0.4%); dizziness (0.3%); and headache (0.2%). The most common adverse drug reactions leading to discontinuation with the 750 mg dose were gastrointestinal (1.2%), primarily nausea (0.6%), vomiting (0.5%); dizziness (0.3%); and headache (0.3%).

Adverse reactions occurring in ≥1% of Levofloxacina Loxadin-treated patients and less common adverse reactions, occurring in 0.1 to <1% of Levofloxacina Loxadin-treated patients, are shown in Table 6 and Table 7, respectively. The most common adverse drug reactions (≥3%) are nausea, headache, diarrhea, insomnia, constipation, and dizziness.

In clinical trials using multiple-dose therapy, ophthalmologic abnormalities, including cataracts and multiple punctate lenticular opacities, have been noted in patients undergoing treatment with quinolones, including Levofloxacina Loxadin. The relationship of the drugs to these events is not presently established.

Postmarketing Experience

Table 8 lists adverse reactions that have been identified during post-approval use of Levofloxacina Loxadin. Because these reactions are reported voluntarily from a population of uncertain size, reliably estimating their frequency or establishing a causal relationship to drug exposure is not always possible.

Levofloxacina Loxadin contraindications

Patients hypersensitive to Levofloxacina Loxadin or any other quinolones or any excipients of Levofloxacina Loxadin. Patients with epilepsy and those with history of tendon disorder related to fluoroquinolone administration.

Use in pregnancy: Levofloxacina Loxadin caused no impairment of fertility or reproductive performance in rats at oral doses as high as 360 mg/kg/day. It was not teratogenic in rats at oral doses as high as 810 mg/kg/day or at IV dose up to 160 mg/kg/day. No teratogenicity was observed when rabbits were dosed orally as high as 50 mg/kg/day.

In the absence of human data and due to the experimental risk of damage by fluoroquinolones to the weight-bearing cartilage of the growing organism, Levofloxacina Loxadin must not be used in pregnant women or women suspected of being pregnant.

Use in lactation: In the absence of human data and due to the experimental risk of damage by fluoroquinolones to the weight-bearing cartilage of the growing organism, Levofloxacina Loxadin must not be used in breastfeeding women.

Use in children: Safety and effectiveness in pediatric patients and adolescents <16 years have not been established. Quinolones, including Levofloxacina Loxadin, cause arthropathy and osteochondrosis in juvenile animals of several species.

Use in

Elderly: The pharmacokinetic properties of Levofloxacina Loxadin in younger adults and elderly do not differ significantly when creatinine clearance is taken into consideration. However, since Levofloxacina Loxadin is known to be substantially excreted by the kidney, the risk of toxic reactions to Levofloxacina Loxadin may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection and it may be useful to monitor renal function.
